Cadbury's Creme Eggs have a hidden code on the wrapper with a surprising meaning... so can YOU guess what it is?

For many Britons, one of Easter's greatest joys is getting their hands on a delicious chocolate egg.

Though the selection of eggs is ever-growing, for many in the UK, nothing compares to the Creme Egg - one of Cadbury's most famous and well-loved chocolates.

Made with milk chocolate and a gooey fondant egg-inspired centre, the delicious treat has been a staple in shops for over 80 years after first appearing in 1963.

Indeed, they're such a classic British Easter favourite that roughly 400 million are sold each year, according to The Mirror. 

While many will no doubt be tucking into their own Creme Egg this Easter, fans of the treat may overlook a hidden code on the wrapper.

Most will rip the foil wrapper and quickly scoff the delicious egg, but if chocolate lovers resist the temptation for a moment longer, they might see a hidden clue revealing how Cadbury's made the egg.

Machines wrap the Creme Eggs at record-breaking speeds by four machines that can get through 50,000 eggs an hour.

The special code allows customers to trace their egg to the specific machine that wrapped it.

Each foil wrapper has the letter W printed on it, followed by a number from one to four.

One of the Cadbury chocolatiers told the Daily Star that the Creme Eggs are not only wrapped specifically but are made in a special way too.

David Shepard, Product Developer of the Mondelēz International Research and Development team told the publication: 'Normally in a chocolate factory when you have a filling, like a Crème Egg, you make a chocolate shell, you set the shell and put the middle in.

'Basically, you deposit the goo centre, the yolk and the white, into liquid chocolate and it very cleverly pushes it out. We call it displacement.'

The chocolate expert went on to reveal that he believes it's the only product he is aware off that is made that way.

He added that often chocolate eggs are made by melting chocolate in to two moulds before fixing the two halves together.

Brits are such big fans of the Easter treat that one has even been caught stealing them.

Last month, a shoplifter was caught with 70 Creme Eggs hidden in his coat.

Video footage showed a police officer unpacking box after box of the chocolate eggs from the shoplifter's Superdry jacket.

Deon De Groot, 26, was stopped as he tried to make a getaway having stolen the Creme Eggs from a Tesco Express store.

The shoplifter had 14 five packs of the sweet treats stuffed in his coat and dozens more boxes were found nearby in a discarded duffle bag.

As he unloaded them from the crook's coat, PC Guy Cunningham said: 'Christ! What have you got in there?'

De Groot entered Tesco Express in Welland Road, Dogsthorpe, Cambridgeshire, at about 11.40am on March 22 and was seen packing the chocolate eggs into a duffle bag before walking off without paying.

In total, De Groot made off with more than 300 of the eggs.
